I was working on a web scrapper to help a client extract and structure data from their old site, when realised I can use pretty much the same tech to solve another problem: monitoring changes on older projects.
It happened quite often, especially on Wordpress projects, that a minor code change from the theme editor or non tech savvy person doing a content updates to have a major effect, broken links, broken layout or even worse.
It also happened that I get to find it out by accident, a couple of days later, so I need a tool to prevent it.
